Title: Ultrathin multiple superconducting wire
Inventor: AKITA MITSUGI
IPC: H01B12/10
Filed: 1989-12-07
Abstract: PURPOSE:To obtain the critical current and critical current density of an ultrathin multicore superconducting wire necessary for practical use and at the same time to lessen the hysteresis loss thereof by having a matrix formed of Cu10%Ni, and setting the filament diameter of each of NbTi filaments to not more than 0.7 micrometer and setting a space between the filaments in the matrix to a value between 0.1 micrometer and 0.15 micrometer. CONSTITUTION:A matrix 2 is formed of Cu10%Ni, and the filament diameter of each of NbTi filaments 3 is not more than 0.7 micrometer and a space between the filaments 3 in the matrix 2 is set to a value between 0.1 micrometer and 0.15 micrometer. In this case, a hysteresis loss proportional to the filament diameter is reduced, and also the space between the filaments is suppressed to be made a little larger than the coherence length of the Cu10%Ni so that a critical current parallel to that of a superconducting wire for DC service may be kept without causing unification of the two adjacent filaments due to a proximity effect. Thus, an ultrathin multicore superconducting wire can be obtained with its sufficient critical current and sufficient critical current density but also with small hysteresis loss.
